...a senior from westport, connecticut... ...and a senior from little rock, arkansas... and now here is the host of "jeopardy!" -- alex trebek! thank you, johnny. and thank you, ladies and gentlemen. hey, i'm still reeling from the ending of our program yesterday, the semifinal in which no contestant wound up with any money at the end of the game. it's never happened before. first time in any of our tournaments, and i was quite taken aback by it. but fortunately, the contestants were more familiar with the rules than i was. so i'm hoping that today, with leonard, emily, and nilai, we have an easier time of it. good luck. here we go into the jeopardy! round. and here are the categories. and you go first, leonard. you know that.
